Description

[Detailed description of the invention] This invention relates to a container for pouring out relatively highly viscous semi-liquid liquids such as creams and pastes, such as cosmetic creams, concentrated milky lotions, and toothpaste. The purpose is to provide a device that does not allow contamination to enter the contents, is convenient to use, and has a simple mechanism. Conventionally,
Semi-liquids with relatively high viscosity such as those mentioned above were generally sold in small bottles with simple lids, but since the contents of the bottle were removed by inserting the tip of a finger into the bottle, it was difficult to remove the contents after use. There were many opportunities for bacterial contamination to spread during storage, which was a hygienic problem.
Therefore, in recent years, devices have been proposed that are hygienic so that contamination from fingertips does not get into the contents when the contents are taken out. The idea published in Utility Model Publication No. 53-15649 is one example. However, although this type of conventional proposal can achieve the purpose of preventing contamination of the contents, it is necessary to remove the bag containing the contents from the outer casing, support it with one hand, and hold it with the other hand. The method of use is complicated, such as pouring out the contents with a strong grip, and the structure is not very simple.

This invention can eliminate the above-mentioned drawbacks of the conventional method by improving the conventional means for preventing the spread of contamination of relatively highly viscous cosmetics and the like after use.

(Structure of the invention) This invention will be explained below with reference to drawings showing embodiments of the invention.

In other words, 1 is a cylindrical container in this invention,
A movable bottom wall 2 is fitted into a cylindrical shape.

A through hole is bored in the top wall 3 of the container 1, and a handle 6 of a push button 4 is tightly inserted into this hole so as to be able to freely move up and down, and the push button 4 has an elastic cap body 5.

A notch 7 is bored in the handle rod 6, and as shown in the figure, when the handle rod 6 of the push button 4 is in the inoperative position raised, the lower side of the elastic cap body 5 is cut into this notch 7.
It continues below the top wall 3 through.

A saucer 8 is bored in the upper surface of the top wall 3, and a surrounding wall 9 that is open on the side of the saucer 8 is provided, and most of the periphery of the elastic cap body 5 is in close contact with this surrounding wall 9.

This invention has been developed as described above, but according to the first embodiment shown in FIGS. In the second embodiment shown in FIGS. 3 and 4, the through hole is bored directly into a plug 11 forming a part of the top wall 3.
What is shown in FIG. 5 is an assembly of the push button 4 and the stopper 11 in the third embodiment, and although the shape of these parts is slightly different from that of the second embodiment shown in FIG. This is shown as an example of the change.

In the first embodiment, the container 1 is made of plastic molding, the push button 4 is made of rubber, 10 is a foot plate provided to prevent the handle rod 6 from being pulled out, and 12 is a protective plate for the movable bottom wall 2 for communicating with outside air. Hole 13 is drilled. It is convenient to provide a simple cap to protect the top surface of the container, but this is not shown.

Regarding the second and third embodiments described above, each part except the assembly of the push button 4 and the stopper 11 described above is the same as that of the first embodiment.

Since the pouring container according to this invention is constructed as described above, the empty space in the container 1 from the movable bottom wall 2 to the elastic cap body 5 of the push button 4 is filled with cream or other contents. Fill it up. At this time, the lower side of the elastic cap body 5 and the inside of the cylinder of the container 1 are connected to the handle rod 6.
However, when the push button 4 is pressed with the tip of the finger, the handle rod 6 is lowered, so that the through hole into which the handle rod 6 is inserted is sealed, as shown in Fig. 3. As a result, the space below the elastic cap body 5 and the cylindrical body of the container 1 are cut off. At the same time, the space below the elastic cap body 5 described above is crushed. Most of the periphery of the elastic cap body 5 is surrounded by the surrounding wall 9 (particularly in FIGS. 1 and 2).
and FIG. 4), and the surrounding wall 9 is open to the side of the saucer 8 bored in the top wall 3 of the container 1, so that it is accommodated under the elastic cap body 5. Since there is no other way for the contents to escape, the contents are poured out into the saucer 8 as the elastic cap body 5 is pressed. Use the poured contents on the tip of your finger. Since the volume of the lower space of the elastic cap body 5 before the through hole is closed by pressing down the handle 6 is constant, the content poured into the saucer 8 by the aforementioned pressing of the push button 4 The amount of objects is almost constant each time the operation is performed. When you release your fingertip from the push button 4 to stop the operation, the handle rod 6 is pulled up by the elastic restoration of the elastic cap body 5, and at the same time, the space under the elastic cap body 5 is opened by the notch 7 into the cylinder of the container 1. Therefore, the contents in the cylinder of the container 1 are sucked up into the space below the elastic cap body 5 through the notch 7, and at the same time, the elastic cap body 5 completely blocks off from the outside air.
Since the content stored in the cylinder of the container 1 is reduced by the amount due to the above-mentioned suction, the volume of the space above the movable bottom wall 2 in the cylinder of the container 1 is reduced by that amount, and this reduced volume is The movable bottom wall 2 is automatically raised by the corresponding amount.

In this way, the contents after use are transferred to the elastic cap body 5.
and the movable bottom wall 2, it is preserved without being exposed to the outside air. Further, after use, the saucer 8 can be kept clean by wiping off any residue adhering to it with a piece of paper or the like.

(Effects of the invention) Thus, according to this invention, the contents of the container are always completely shielded from the outside by the elastic cap body 5 and the movable bottom wall 2 when the container is not in use, such as during storage or transportation. Therefore, it is not subject to chemical changes due to air oxidation, etc., and is also protected from contamination by fingertips. In addition, according to this invention, the contents can be poured out with one finger operation while the container is placed on the table during use, which is very convenient, and the contents can be taken out periodically after each operation. It is extremely economical because the contents are poured out with almost no residue and are consumed without wastage. Furthermore, since the pouring container according to this invention has an extremely simple structure as a pouring container with such a valve, the production cost is low and it is highly suitable for mass production. Therefore, according to this invention, it is possible to provide a convenient, clean, and inexpensive pouring container for creamy or pasty substances for daily consumption.
